The first non-leaking ballpoint pen was invented in 1935 by the Hungarian brothers Lazio and Georg Biro. Lazio was a chemist and Georg was a newspaper editor. A ballpoint marker had been invented much earlier in 1888 by John Loud, an American leather tanner, who used the device for marking leather. But Loud’s marker leaked, making it impractical for everyday use. A new type of ink had to be developed; this is what the Biro brothers did. The brothers patented their invention and then opened the first ballpoint manufacturing plant in Argentina.
